PowerMac G5 Quad Power Consumption

Hello
I purchased a brand new Apple PowerMac from the online store.
Quad PowerMac G5
250GB HDD
1GB RAM
Standard VGA Card - GeForce 6600
Can anyone tell the exact power consumption when idle and maximum use.
Many thanks.
Haresh Kainth

Unfortunately, that document only addresses idle
power consumption, which is of limited use. You might
be able to estimate monthly energy cost from this, if
the computer is mostly idle, but you can't tell how
big a UPS to buy.
I think this is the link tele_player is referring to.

Quad G5: Actual Power Consumption

I haven't seen the numbers posted, so I thought I'd share from this config:
Quad 2.5 Ghz G5 (Rev A, dual pumps)
4.5 GB PC2-4200 RAM (4 x 1 GB, 2 x 256 MB)
Geforce 6600
Western Digital 250 GB SATA Drive (WD2500JS)
Seagate 400 GB SATA Drive (ST3400832AS)
No firewire or USB devices connected (except keyboard, mouse)
Here was the measured power consumption (in watts):
455 Peak measured (with 4 CPU's at 100%, disks writing)
275 Idle (CPU at Highest)
245 Watching a DVD (CPU at Automatic)
210 Idle (CPU at Reduced)
43 Mac Sleeping
The specs page lists "At least 10A" required at 120 volts. Even if you squeezed 9 drives into the G5, I don't see how one would ever approach 1200 watts.
I use a Belkin 1500VA (830 watts) UPS, which is 55% loaded when the Quad is at its peak, and can sustain that for around 10 minutes.
At 7 cents per kWh, running BOINC could cost 77 cents per day, running idle would be 36 cents, and sleeping 8 cents.

I posted similar results a few months ago. Amazing that people were worried (when the Quads first appeared) that they'd have to run new power lines to support them.
I used a 'Kill A Watt' to measure - what did you use?

Power Consumption Quad-Xserve w max RAM?

Hi,
actually our "old" dualcore Intel xserves consuming approx. 260 Watts (4 RAM Bars, 3 HDDs).
unfortunately there are no Power Consumption Charts for the actual Quad-Core Xserves. Can someone gimme an average value: 3 Ghz Quadcore, 3 HDDs, fully plunged RAM Bank? Shure, it depends on the serverload... roughly speaking... at moderate load?
thanks

What Apple might recommend and what might work in your environment, I do not know.
The APC SmartUPS 1500 works reasonably well for an Xserve and its usual accretion of giblets and accouterments, and Mac OS X Server automatically recognizes this device via its USB connection.
And one thing I've discovered that's not widely listed. Get yourself some short power cords. A handful of appropriately-rated power extension cords (of about one foot in length) makes most UPS products far easier to deal with. These cords are a few dollars each from various vendors, and very useful.

XServe dual quad core max power consumption

What can I expect to be the max power consumption of a dual quad-core XServe?
I have four new XServes that I administer in four separate locations and I need to know what Apple recommends for an Uninterrupted Power Supply (UPS) per server.
Right now, I have a 500VA one that I've had on hand at least one site. However, I've noticed that this one, eventhough the UPS has a new battery in it, does not support an XServe -- ie, when I test it, the XServe shuts down abruptly. My guess is that 500VA is inadequate.

Power consumption for latest mac pros?

I read on Apple.com somewhere that the 2008 Mac pro's maximum power consumption is 260+ Watts for a Quad-core. How different is it for the new Mac pros?

I guess English is a lost language now.
For the Mac Pro it is really really simple and based on 7 yrs of PowerMac G5s and then Mac Pro owners: 1500VA - you can get by with slightly smaller 1300VA and some people, because of better build, used SMART UPS 1000VA.
And as I said in another thread, the Mac Pro 'suffers' from inrush current that can knock out smaller UPS, and people that have tried to use 500-900VA units got into a lot of trouble and had to upgrade.
No one can know the total system watts used other than use a KILLAWATT on the power cord.
Look at the case, can an iMac dispel as much heat as easily? no. It is designed for lower power and much fewer components.
Core i7 has HyperTransport and Turbo boost for one thing. Apple had a huge coding problem with audio (incl iTunes and others), flash and Nehalem based systems. High cpu temperature and lost processor cycles and performance.
The 2010 Mac Pro can do more for the same, and DDR3 lowered heat and watts noticeably.
There are sites where you can plug in various components and get an idea of how large a PSU would be needed. Try one of those, too. PSU efficiency, and there is "overhead" needed for the motherboard chips and to run PCI Express for graphics, Firewire, etc. It all adds up.
Apple's example is low-end system configuration, the chart says CPU MAX, not SYSTEM (but then, most everything on hardware requirements lately needs a grain of salt).
Quad-core 2.66GHz configuration:
One 2.66GHz Quad-Core Intel Xeon "Nehalem" 3500 series processor,
3GB memory (three 1GB 1066MHz DDR3 ECC DIMMs),
640 GB Serial ATA 3 Gb/s 7200-rpm hard drive,
18x double-layer SuperDrive,
NVIDIA GeForce GT 120 with 512MB of GDDR3 memory
APC we know, whether PowerMac 2.0DP from 2003 or Quad G5, or Mac Pro, that 1500VA is strongly recommended.

2011 MacBook Pro hard drive power consumption

Does anyone know the differences in power consumption between the Apple-supplied 750GB 5400rpm HDD, 500GB 7200rpm HDD, and 256GB SSD drives? I'm currently using a 2011 MacBook Pro with an Apple-supplied 256GB SSD and I'm getting between 5-8 hours of battery life, depending on what I'm doing. I wish it could get closer to a full 10-hour battery life for longer trips, but I realize there's a price for performance. What's the best hard drive option to minimize power consumption? Are there any other tips for increasing battery life? Does it make a difference if you turn off Bluetooth and WiFi when you know you're not going to be able to use them? Thank you in advance for your reply.

Yes, turn Wi-Fi and BT off when not needed. That and your screen are the biggest power consumers. Keep the brightness as low as you can to conserve power.

Average power consumption comparision: i7 and t500

Hi,
What is the average power consumption (non-peak) of a t500 system,
doing web-surfing and light tasks ?
I have read that the i7 mobiles (non-lenovo) are at 52W avg, and 75W peak,
and this will help me decide whether to buy the t500 or wait for the lenovo
i7 based laptops
thanks!

P8400 / P8600 etc core2duo mobile (2,2-2,4ghz) take 25W. I think in office use my T400 uses about 15W, not sure. It depends on load. I find quad core laptop CPUs quite useless for the average user.I think the i7 mobiles have a 45W specification, which is quite higher than the modern dual cores. I prefer longer battery life to having four cores i will most likely never use in daily work. This changes, of course, if you use your laptop as Desktop replacement or primarily for CPU intensive tasks, such as video en/decoding.

Will the new ATI graphics card work on PowerMac G5 Quad?

Hello,
I'm having a problem with my PowerMac G5 Quad, simply the graphics card is at fault. The rest of the machine is in perfect working order. I need a new graphics card and i've searched ebay (UK) and found some products. However, I would like a new graphics card with a little more power.
As I develop code using the OpenCL API on the windows machine, I would like to transfer this process over to my Mac (have to install OpenCL API myself, as Leopard does not have native OpenCL support). More importantly, OpenCL supports selected GPU types i.e. latest GPUs from ATI/Nvidia.
Simply put, would anyone know or have experience installing the newer ATI/NVIDIA generation of Mac Graphic cards on PowerMac G5 Quads and if so, which graphic card (ATI RADEON 4850 etc).
As I think about this, both PowerMac G5 Quad and Mac Pro utilise PCI-E and yes, even though graphics cards are not particularly interchangeable on different architectures (or are they?) I would just like to know if anyone can give me advice or if anyone has had success or failure at such an attempt.
I really cannot afford to buy a Mac Pro machine and there is still many years of life left in my PowerMac G5. I really need your help and advice friends.

Hi-
Welcome to Discussions!
No modern card will work in a G5.
The best that one can do in a PCIe graphics G5 is to use a flashed Geforce 7800 GTX 512MB card.
That card is the pinnacle of GPU power for a G5.
There are no options beyond that.
Here is a full, "short" list of options:

PowerMac G5 Quad doesn't start up (crashes and fans become real loud)

Hi all,
I started having problems with my PowerMac G5 Quad 2.5GHz (late 2005) about a week ago. First I found the computer with the fans running at full speed (really loud) after leaving the computer alone for a while (instead of going into Sleep mode). At this point, I wasn't able to recover it from that state and had to force it to shut down by holding down the power button. Another thing that caught my attention was that a couple of red LEDs were on (just behind the power button).
Last night, after finding the same situation and shutting down the computer, it would no longer start up. I could hear the hard disk starting to spin and the chimes sound, but I'd get no video at all (no gray screen or anything). After trying 3-4 times, the computer finally started up.
The situation got worse this morning, as again I found it with the fans on full blast. Now I can't get the computer to boot anymore. I no longer here the chimes sound or get a video signal at all. I can't open the CD tray either (it doesn't seem to recognize the keyboard) so I could not boot from a CD. And holding down the power button is no longer shutting it down, now I have to unplug it.
I've already tried relocating the RAM, resetting the SMU, and read about resetting the NVRAM (however, this was not possible as I have no response from keyboard input).
I've not installed any new software or hardware lately so maybe this was caused by the latest software update. After reading forums and searching the web, it looks like this problem has become quite common in the past few weeks. Has Apple taken any steps to solve this problem on the affected computers?
Any ideas or suggestions would be of great help. Thanks!

Man it sounds like what happened to my G5 quad before it died. Sounds like your power supply is done. There is a link on the lower right side on the SUPPORT page under EXCHANGE AND REPAIR PROGRAMS... There is a recall on the power supply of these models but Apple is not honoring it. Here is my story:
In April of 2009 My Quad dies and won't start. I bought this machine in January of 2006. I bring it into the Apple store and they said it is the Power Supply, but will cost over $500. I decide to buy a MacBook Pro due to the intel chip needed for newer programs.
August 2009- I find that Apple has announced a program to fix the Power Supply on the G5 Quad. (I guess they did not know about this repair program in April at the Apple store in Kahala, Hawaii). I figure that even though my computer is just over 3 years old they will surely fix it for free. Nope. Denied. "You gotta pay son".
Imagine if a car company announces a recall on a part that will render your machine inoperable and then denies to fix it.
I am very upset. If this does not get fixed for free I will not stop bad mouthing Apple until the day I die.

Power consumption on sleep

After upgrading to Mavericks, I have noticed that the power consumption on battery on my MBP when in sleep with the lid closed is way up. 99% charge when puting the computer to sleep, 45% after 12 hours when opened. What gives? Any suggestions?

Actually, the APC 1200XS works fine if and only if the G5 is already powered on. I'm running a stock Quad G5 + and extra 4GB of RAM, but nothing else off of the UPS.
It's actually not uncommon to have appliances that draw significant currents/power on startup that exceed the basic circuit rating. Things like motors/pumps can draw large currents on startup. Circuit breakers and fuses need these high current levels to be present for periods longer than the lifetime of an inrush current situation. Most reactive components, i.e. the inductors and capacitors, in a large power supply like the Quad G5's only take few 10's of milliseconds to charge up, so the high draw subsides quickly.
I'd also be surprised if your APC 1500XS doesn't have the same issue as I have since my guess is that APC builds a class of UPS with the same basic electronics on the input side and then just modifies the output side a bit along with the battery capacity. You can test whether you have this issue as well by putting the machine to sleep, pull the UPS's plug from the wall and then wake up the computer (if it doesn't wake due to the power being lost).

I'm guessing that my Powermac G5 Quad running 10.4.11 does support extended desktop. My present monitor is a 1600x1200. Can a second monitor of smaller size and lower resolution work as an extended desktop?

Software or Games for a Powermac G5 Quad?

I recently got a Powermac G5 quad that was in storage for a long time so its basically brand new still and i was luckily enough to get it for free.. It has 16Gb ram and 6600 Nvidia graphics. I know that its very dated and no software can really run on these things now. I just really wanna push this thing to the limit and test its power out with any software or games that can still run on these things. As i should i am running 10.5.8 thanks for any suggestions.

PowerMac G5 Quad, Turn Of Processor 2 3 4?

Hi all.
Just a quick query, Ive noticed this, but i've been using Xcode for about 2 years and in my System Preferences there's a new option, named Processor (under Hardware).
When I open the Processor panel, it allows me to un-tick processors 2, 3 and 4. Now, does this mean, if i disable 1 or all processors, that it completely stops and powers down the core?
Or do these option simply mean, that no instruction(s) are sent to the un-ticked core but all cores are still consuming normal amounts of energy.
Example, Go to System Preferences > Processors. If I un-tick processors 3 and 4 (but leave processors 1 and 2 ticked), that processors 3 & 4 are turned off (meaning powered down to a sleep status). And only processors 1 & 2 are running normally.
Another thing, should I decide to un-tick processors, is this a safe thing to do for a long period of time (yes a stupid question, but Im unsure).
I hope I've explained my issue clearly
Anyway friends thanks for reading and I hope someone can shed some light.
Harry.

You should take into consideration that an enabled, but idle core does not take very much energy, i.e. the difference between a disabled/off and an idle core is much less than the difference between an idle and a busy one -- the power management of the chip puts most units to sleep when idle.
The only real way to save energy is to give your computer less work, otherwise you'll simply have one core working longer, rather than four cores doing the work much faster (assuming that your workload has thread or task-level parallelism).
So if your computer is running more with one core instead of less with four cores it might even end up using more energy (because all the other components) if you don't reduce the workload... What does work well is limiting the peak power consumption by disabling cores.
Ciao, Colin
PS: My solution to the energy problem was to sell my Quad G5 and get a MacBook Pro dual 2.4 GHz

Powermac G5 quad - where ist the SMU-Reset Button?

my G5 quad is very fast, but too loud. The Main Logic Board Backside Fan increases speed after maximal 5 Minutes up to 3000 rpm, even if the quad really does nothing. I tried to reset the SMU by removing the power cord, but no difference.
An Apple instructor sent me this:
"To reset the SMU on a Power Mac G5 (Late 2005) computer, either use the steps listed above for the Power Mac G5 (Late 2004) or:
Turn off the computer by selecting Shut Down from the Apple menu or by holding the power button until the computer turns off.
Open and remove both the metallic outer door and the inner plastic air deflector.
Remove the fan assembly immediately to the left of the processor module.
Press the SMU reset button on the logic board.
Replace the fan assembly, air deflector, and outer door.
Turn on the computer."
…but I can't find the SMU reset button. Can anybody help me?

Hello
Choose "turn off" in the Apple menu, unplug the power cord, open the side door, unplug the lower fan, put your hands on the Quad Tower Case before you touch the SMU Button, then push the button only one time.

PowerMac G5 Quad - boot up weird problem

Hi there! It's my first post.
I bought a nice PowerMac G5 Quad in great condition, super cheap. Installed OS X 10.5 after adding 2 TB hdd. Went really well i thought.
I was in the OS having a look around and shut it down. Left the power unplugged for about 24 hours.
After that things got a bit strange.
On startup I have to unplug keyboard and mouse (I read the suggestion on the Apple support site and it worked) I also read about the startup disk needing to be reselected and did that but it is still happening.
Im using an old model of the Mac keyboard (has 1 usb on either side) and a Dell mouse.
How can I correct this permanently? its a bit of a pain doing it every time. Is it the version I installed? Do I need to take it up to 10.5.8?
Seems to work normally after its booted though.
I am an Infrastructure Engineer who has only just started moving into the Mac OS X, so would say i'm technically solid but Mac skills are low. I learn fast though :)
Cheers!

Hi Tom.
Thanks very much for your advice. I purchased another pram battery yesterday and installed it as you suggested.
The same problem was still happening. I just couldn't get the Mac to boot correctly.
I ended up reinstalling 10.5 from scratch and then doing the update to 10.5.8 straight away.
This seems to have worked as I have shut down and then started 3 times as well as doing a starlight restart from the OS.
Everything is looking good so fingers crossed tonight when I get home I'll ave no trouble and start installing some apps.
Thans again.
